Android was the first mobile OS to introduce scrollable background in the main homescreen which allowed users to have their favourite widescreen wallpapers as backgrounds in their phone.
Scrollable backgrounds in iPhone are now possible, thanks to Parallax, an iPhone app for jailbreaken devices. You can easily flick through icons in your iPhone homescreen with the wallpaper scrolling with each screen in the background.
Bored with the same look and feel of fonts on your iPhone or iPod Touch? Well, now you can get it a new fresh look with custom fonts using an app called Font Swap from Cydia.
How and where to get the app can be seen in the video I’ve attached below and everything is explained in it with all the details you need with step-by-step instructions.
